JURGEN. PETER LANGE, OF BUTLER, NEW JERSEY.

PIPE-STEM.

SPECIFICATION forming part of Letters Patent No. 296,417, dated April 8,1884.

Application filed January 28, 1884. (No model.)

To all whom it may concern:

Be it known that I, JURGEN P. Lands, of Butler, in the county of Morrisand State of New Jersey, have invented new and useful Improvements inPipe-Stems, of which the following is afull, clear, and exactdescription.

My invention relates to improvements in pipe-stems; and it consists inthe peculiar construction and arrangement of parts, as hereinafter fullydescribed, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 represents a longitudinal section of a pipestem embodying myinvention,with mouth-piece attached, as also the bowl, which is shownpartly broken away at its connec tion with the stem. Fig. 2 is alongitudinal exterior view of the central main or core portion of thestem, with a surrounding-tube in section. The stem, which may be made ofhard rubber or any other suitable material, consists of a main orcentral portion, A, and an outer casing or tube, B. The main piece A,which screws or otherwise fits at its lower end into the bowl 0, isconstructed, for a short distance up said end, with a straight hole, b,that communicates with a small branch hole, 0, lead ing to and throughthe side of the piece A, where it connects with the lower end of aspiral groove, (1, formed in and around the exterior of the corepiece A,said groove preferably being of such pitch as to make it of considerablelength for 'a comparatively short length of stem. The upper end of thisspiral groove connects in like manner, by a side hole, c, with aprolonged central hole, f, in the piece A. This hole is separated fromthe lower longitudinal hole, I), by a partition or solid portion,

The tube B, with which the mouth-piece D connects, is made to fit snuglyover the central piece, A, inclosing the spiral groove (1, and is formedslightly flaring at its lower end, h, to fit a corresponding taper, 11,on the lower end of the piece A, whereby the tube will be securely heldto its place, and will admit of easy removal when required to clean thestem, which may be done with very little trouble.

In the top of the piece A is a small hole,

8, connecting the hole f with the mouthpiece or with a small chamber, m,between the mouth-piece and upper end of thepieceA. The separation ofthe holes I; and f by the parti tion 9 makes the longer hole f areservoir for nicotine rising with the smoke through the holes I; c andspiral groove (2, and from thence by the side hole, 6, into the holef,where the nicotine is deposited, while the smoke passes out by theaperture 8 to the mouth-piece. The separation of the nicotine -reservoirf keeps dampness from the bowl. What little nicotine may beprecipitated. in the mouthpiece will pass out through the aperture 8into the reservoir f, the upper end of the piece A being cup-shaped onits exterior, as at n, to collect and conduct such nicotine to theaperture s,- and this aperture 8, by reason of its central position andreduced size relatively to the hole or reservoir f, will prevent anynicotine passing from the reservoir into the mouth-piece when the pipeis tipped or laid on one side.

I am aware that a hollow core divided into two compartments and providedwith spiral grooves on its outer surface communicating with saidcompartments has been incloscd claim such invent-ion.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a pipe stem, the combination, with thespirally-grooved core A, having-the longitudinal passages 72 f and thetransverse passages c e, of the outer casing, B, having the mouth-pieceD secured to it, and projecting beyond the end of the core to form thechamber m between its end and the end of the core, substantially asherein shown and described.

2. In a pipe-stem, the spirally-grooved core A, having its upper endcup-shaped, as at n, and provided with longitudinal passages I) f,

.within an outer shell, and I therefore do not the transverse passages ce, and the hole 8, v

in combination with the outer casing, B, having the mouth-piece Dsecured to it, and pro jecting beyond the end of the core to form thechamber m, substantially as herein shown and described.
